Function Features

• Working Principle: Three-phase alternating current generates rotating magnetic field inside stator winding; high-performance rare earth neodymium iron boron permanent magnet rotor follows magnetic field rotation, resolver sensor feeds back real-time rotor position to servo drive to realize closed-loop vector control, achieving precise torque, speed and position regulation with ultra-high torque-inertia ratio
• Ultra-high dynamic acceleration performance, machine cycle time reduced by 30% compared with asynchronous servo motors of same power grade
• Smooth cast aluminum housing surface, anti-adhesion to dust and production process debris
• Low cogging torque design, torque ripple ≤1% rated torque for ultra-smooth low-speed operation
• Integrated rear terminal box with separate power cable and feedback encoder cable connectors, convenient wiring separation
• Compatible with Baumüller servo-hydraulic pump direct drive, packaging machine linear actuator, textile loom small motion axis
• Energy-efficient permanent magnet design, average power consumption reduced by 22% vs conventional asynchronous servo motors

Material Composition

• Motor Housing: Die-cast aluminum alloy with surface passivation anti-corrosion treatment
• Stator Core: Cold rolled silicon steel laminated sheet with low iron loss coating
• Rotor Permanent Magnet: High remanence neodymium iron boron rare earth magnet, high temperature resistant grade
• Front/Rear Bearings: Double row sealed deep groove ball bearing with long-life food-grade lubricating grease
• Shaft Seal: Nitrile rubber rotary shaft oil seal for IP65 dust and water splash protection
• Terminal Box Enclosure: Reinforced PA66 flame retardant plastic, UL94 V0 fire resistance

Structural Characteristics

• Compact cylindrical frame size 28 miniature structure, small footprint for tight mechanical installation space
• Front circular B5 mounting flange with four symmetric M4 threaded mounting holes
• Separated dual cable terminal ports on rear terminal box: power cable connector and resolver feedback connector independent layout
• Integrated axial cooling rib structure on aluminum housing for natural air convection heat dissipation without auxiliary fan
• Internal stator winding vacuum impregnation process to eliminate winding vibration noise
• Rear resolver feedback unit sealed independent cavity, isolated from motor winding heat source to avoid temperature drift of position signal

Application Scenarios

• High-speed small packaging machine cutting and labeling motion axes
• Textile loom micro yarn tension control servo axes
• Medical pharmaceutical automatic filling equipment precision positioning drive
• Small desktop industrial robot joint miniature drive units
• Plastic injection molding machine tiny ejection auxiliary motion axes
• Electronic PCB assembly pick-and-place micro positioning servo

Installation Requirements

1. IM B5 horizontal mounting recommended; IM V1 vertical installation requires additional shaft drip protection cover to prevent liquid ingress
2. Mounting flange contact surface flatness error ≤0.05 mm/mm to avoid bearing eccentric load damage
3. Flexible coupling must be used between motor shaft and mechanical load; rigid direct connection causes shaft overload fracture
4. Cable wiring reserved bending radius ≥10 times cable outer diameter, avoid sharp angle bending
5. Power cable and feedback signal cable must be routed in separate shielding trunking to eliminate electromagnetic interference
6. Ambient installation must avoid continuous oil mist, chemical vapor and water splash beyond IP65 protection limit

Operation & Maintenance Precautions

1. Do not operate motor continuously under 300% peak overload torque exceeding 3 seconds; long-term overload causes permanent magnet demagnetization
2. Check bearing noise every 6 months; abnormal buzzing noise indicates bearing grease failure requiring replacement
3. Clean motor housing cooling ribs regularly to prevent dust blockage leading to winding over-temperature alarm
4. Avoid impact collision on motor shaft during installation; resolver position sensor will be damaged by axial impact force
5. After long-term storage over 12 months, perform low-speed idle running for 30 minutes before formal load operation to restore bearing lubrication
6. If resolver position feedback signal loss occurs, check rear terminal box connector pin loosening or cable internal breakage
